SIHOO Doro S300 Ergonomic Office Chair with Dual Dynamic Lumbar Support,Home Office Computer Chair, 6D Coordinated Armrests, Adjustable Rolling Chair (Black)

The best chair for my pain areas. This chair really helps with my slouching which causes alot of these issues. It helps me sit properly without any discomfort. The chair literally feels perfect in every single way. I was skeptical at first before dropping a ton of money on this, but with the help of ChatGPT, it narrowed my decision to this vs other chairs as well as the features.Build Quality A+Ease of Assembly A+Functionally A+Sturdiness A+FYI, I'm 5'5 and this is perfect for my height. I love that it's adjustable, breathable and all around a very comfortable chair to work long hours in.

Very happy to purchase this chair. As a patient of cervical spondylosis, this chair supports my neck very well and provides just the right amount of support at the waist and elbows. After installing it and just testing it for a while, I ordered a second one for my husband.

Updated: Sihoo replied and willing to improve on this issue and refund it.I wanted to love the Sihoo S300. The upholstery is great and the build feels sturdy. But the leg design is fundamentally flawed, causing the casters to drag and lock up on every turn, even on perfectly smooth floors.When I email them about the issue, SIHOO support said this is normal because the wheels are "anti-slip" and offered a $25 credit to buy aftermarket replacements caster. That is not a solution. The chair’s base is poorly engineered and no amount of lubrication or new caster wheel will fix it.For a premium-priced chair, this performance is unacceptable. If you need easy maneuverability, avoid the S300 or be prepared to stuck while moving it. Buyer beware!

I spent weeks mulling back and forth between this, the Hbada E3 Pro, Hinomi X1, and a used Steelcase Leap.The motivator that pushed me to purchase this chair was catching it during a lightning deal, with an additional 10% coupon. My total was $577 all in.Some assembly required, but it shouldn't take you more than 15 minutes. My initial impression of the chair has been great. I work from home and spend 10+ hours a day sitting at my computer. There is a lot of flexibility to support your seating preference. The mesh is nice and soft and there is just enough give to provide a nice cushion, it could be a little more give if I am being picky.Like some other, mine arrived three days past the estimated delivery date. With two days where it was "out for delivery" and never actually made it to my door.btod.com (behind the office door) provided the best review on this chair. One video produced by them was the initial impression, and then a second video was produced as a follow-up.

It broke after 6 month of using. The chair is tilting both backward and forward… I almost fell flat on my face to the floor. I’ve gotten $11 for a refund on $640 useless chair. It cost more than $50 to trash it. Stay away from this brand at all costs.Update: Company issued another $5 in refund. They think that this is some kind of a joke. This company really need to go out of business.Update 2: Mfg offered full refund, but I really don’t know if I have to break my principal after they toyed around with two ridiculously silly refund attempt.

The Sihoo S300 is a remarkable ergonomic office chair that combines comfort, functionality, and aesthetics. As someone who spends long hours working at a desk, and with a serious chronic back injury, I've been thoroughly impressed by its thoughtful design and attention to detail.Ergonomic DesignThe S300's ergonomic design is its standout feature. Here's why I love it:- Adjustable Headrest: The headrest can be customized to support your neck and head perfectly. Whether you're reading, typing, or taking a break, the headrest ensures optimal comfort.- Lumbar Support: The built-in lumbar support is a game-changer. It promotes proper posture and alleviates lower back strain. I appreciate how it adapts to my spine's natural curve.- 3D Armrests: The armrests are adjustable in three dimensions: height, width, and angle. This flexibility allows me to find the ideal position for my arms, reducing shoulder tension.- Breathable Mesh Back: The mesh backrest keeps me cool during long work sessions. It's both supportive and breathable, preventing that uncomfortable sweaty feeling.- Tilt Mechanism: The chair's tilt function lets me recline slightly, promoting blood circulation and relaxation. It's perfect for those moments when I need a brief break.- Height Adjustment: The gas lift allows easy height adjustment, ensuring my feet rest flat on the floor. No more dangling legs!Build QualityThe S300 feels robust and well-constructed:- Sturdy Base: The five-star base provides stability, even when I lean back.

The instructions were clear, and all necessary tools were included. Within 20 minutes, I had a fully functional chair.Customer ServiceSihoo's customer support deserves a shout-out. When I had a minor issue with the armrest adjustment, they promptly sent replacement parts. Their responsiveness impressed me.The Sihoo S300 is more than just a chair; it's an investment in comfort and productivity. If you're serious about maintaining good posture and enhancing your workspace, I wholeheartedly recommend it. Five stars!

A lot of money to find that in the forward position, the seat slips on one side, constantly. On the positive side, the back support is great, the head rest is great, the fabric is great, the adjustable arms are great. But, if you can't sit without an issue with the seat all is for naught. Customer Service hasn't been helpful yet. I'm hopeful. I will update my review based on what happens with the seat.
